🧬Lab 1: The “Lie Detector” Lab (Body Language & Deception) Summer Internship

[ LAB 01 ] THE “LIE DETECTOR” LAB

BODY LANGUAGE & DECEPTION

01: 🚧MISSION BRIEFING

Have you ever felt like someone was lying to you, but you couldn’t prove it? Welcome to the world of Micro-expressions. In this lesson, we are going to hack the human face. You will learn that the human brain is a “whistleblower”—it often tells the truth through facial muscles before the mouth even has a chance to tell a lie.

 

 

02: 🧠THE SCIENCE (BRAIN VS. WILL)

When we experience an emotion, our Limbic System (the honest, reactive part of the brain) sends a signal to our facial muscles immediately. If we are trying to hide that emotion, our Prefrontal Cortex (the thinking, “poker face” part of the brain) tries to suppress it. The result is a “glitch.” For 1/25th to 1/2 a second, the true emotion leaks onto the face. It is involuntary, universal, and impossible to stop completely.

 

03: ⚙️CORE COMPETENCIES

📏 Action Units (AU)
Understand how specific facial muscles create “Action Units” that signal real emotion.
🌍 The Big 7
Master the 7 universal emotions: Anger, Fear, Disgust, Contempt, Joy, Sadness, Surprise.
🎭 The Leakage Factor
Spot the exact moment a “Social Mask” slips to reveal the “Forensic Truth.”

04: 🔬LAB OBJECTIVES & VOCABULARY

Identify the “Micro-flash” of Disgust vs. Anger.

Understand why “Contempt” is the most dangerous micro-expression in an interview.

Micro-expression: A brief, involuntary facial expression that appears when concealing an emotion.

F.A.C.S. (Facial Action Coding System): The “Gold Standard” forensic tool used to categorize expressions.

⚠️ THE “PERMANENT INK” CONNECTION

“In the old days, a lie happened and it was gone. Today, the internet is written in permanent ink. Because we live in an age of recorded video, we have the ultimate forensic tool: The Pause Button. A 0.5-second mistake made today can be analyzed by experts 10 years from now. You can delete a post, but you can’t delete the ‘tell’ you left behind.”

Course Content

🧠Module 1: The 0.5 Second Truth (Micro-Expressions)
We introduce the "Action Units" of the face. Students learn that the brain is faster than the will; before a person can craft a lie, their face flashes the truth for 1/25th of a second.

🚨Module 2: Baselines & Red Flags (The Navarro Method)
THE "BIG 7" UNIVERSAL EMOTIONS Forensic psychologists have discovered that no matter where you live in the world, human beings show these 7 emotions exactly the same way. We call these Action Units (AU). 1. Anger: Brows lowered and drawn together, vertical lines between the brows, eyes bulging. 2. Fear: Brows raised and pulled together, upper eyelids raised, mouth slightly open and tensed. 3. Disgust: Nose wrinkling, upper lip raised. (The "Something Smells Bad" face). 4. Contempt: One corner of the mouth is pulled up (The "Smirk"). This is the only asymmetrical expression and is a major red flag in forensic interviews. 5. Joy: Cheeks raised, "crow's feet" wrinkles around the eyes. (If there are no wrinkles by the eyes, the smile is fake!) 6. Sadness: Inner corners of the eyebrows are raised and pulled together. 7. Surprise: Eyebrows raised, eyes widened, mouth open. (Lasts less than a second).

🧪Module 3: Permanent Ink – The Digital Autopsy
Why does this matter for your digital life? The Pause Button is the Liar's Worst Enemy. In a real-life conversation, a micro-expression is almost impossible to see with the naked eye. But on the internet, everything is recorded. Forensic experts can take a "Storytime" video where a creator is claiming they were "so sad" about a situation, and they can play it back at 0.25x speed. Suddenly, that "sadness" is revealed to be a micro-flash of Contempt or Joy (Duping Delight). Once you post it, the evidence of your true feelings is trapped in "Permanent Ink." [AI VIDEO PLAYHOLDER] [INSERT VIDEO: "Micro-Expression Training Tool"] In this video, watch the "Flash Frames." An image will appear for only 1/15th of a second. Your mission is to identify which of the Big 7 emotions you just saw. Record your answers in your Digital Lab Notebook.

📁Module 4: The Lie Detector Lab (Interactive Assessment)
Look at the three scenarios below. Which emotion is likely "leaking" through? Scenario A: A student says they are "happy" for their friend who won an award, but for a split second, the left corner of their mouth twitches upward in a smirk. Forensic Finding: Contempt. They actually feel superior or resentful. Scenario B: A YouTuber is apologizing for a mistake. They are crying, but their eyebrows are flat and their eyes are wide open. Forensic Finding: Performative Sadness. Real sadness requires the inner eyebrows to pull up and together. Scenario C: You ask your sibling if they ate your snacks. They say "No," but their nose wrinkles for a fraction of a second. Forensic Finding: Disgust. They are disgusted by the lie or the "grossness" of being caught.

🛡️STUDENT “MISSION” (Final Project)
The Assignment: "The Virtual Vibe Check." Students must find a 60-second clip of a public figure being questioned (e.g., a press conference or talk show).

🧱LESSON SUMMARY
Micro-expressions are involuntary "leaks" of emotion. They happen because the Limbic System is faster than the Prefrontal Cortex. There are 7 Universal Emotions that everyone on Earth shares. In the age of Permanent Ink, we can use digital tools to "freeze" these moments and find the truth.
